CONTACT:Mustapha Amrani
DESCRIPTION:Depth imaging and inversion of seismic data is becoming common
 place within the seismic industry. However the inversion procedures used t
 oday have a highly non-convex objective function and will often fail unles
 s careful multiscale processing has been included in the workflow. In this
  talk\, we will review some approaches to improving the robustness of the 
 procedure.\nBecause the PDE-constrained inversion procedure used in indust
 ry can be very expensive due to the large number of PDE solves required\, 
 we will review and address some of the numerical challenges in this area. 
 The talk will concentrate mainly on computational developments and will be
  illustrated with industrial examples from full waveform inversion of seis
 mic data.\n
